Excellent service from Heatco St Albans
Annual boiler service completed. Also, recently dealt with an emergency repair as the system pump had broken down. Heatco provided a prompt, professional and friendly service. Arrived on time for the appointment and let me know they were on their way. Easy to book a service on their website. I was told to contact them if any problems arose, but it has not been necessary. Happy customer.

Brilliant service
Darren recently did a gas safety check on my rental property. He arrived on time, completed the relevant checks and even took the trouble to go and buy a missing carbon monoxide alarm and come back later to install it. That extra level of service was really appreciated and I can’t thank him enough. I would definitely recommend HeatCo.

Excellent Service
Darren performed a boiler service for us and fitted a new thermostat unit. I had previously stated that this might be needed as the control unit had physically broken and had lost contact with the boiler unit. I received a call well in advance of the expected start time to say that he had been delayed on his first job and would be about 30 minutes late which was considerate and he subsequently arrived on time. Darren worked quickly to perform the service, confirmed the thermostat change was required and explained the outcomes of the tests he had carried out. Later that day we received the gas certificate. I would definitely recommend HeatCo, they fitted the boiler and are our first contact if anything should go wrong.

Excellent work
Wholeheartedly recommend HeatCo. Easy booking of appointment for Combined Boiler Service and Gas Safety Certificate. The online system confirmed booking immediately and provided 2hour slot on the chosen date. Friendly, efficient service and small repair of boiler. Landlord and gas certificates were issued and emailed the same day. Thank you very much HeatCo.

Darren arrived on time to service the gas boiler. As usual Darren just got on with the work and left everything clean and tidy after he had completed the service. I would certainly recommend Darren and HeatCo.

Darren was excellent, called me early, arranged to come to site before the appointment and it was done and dusted in just over 30 minutes. Always polite and friendly and cleaned up after. I can’t recommend HeatCo any more highly!

Faulty Flush Button on a Toilet
Darren came, identified what was causing the problem, nipped out to purchase a replacement flush push button, and fitted it, leaving the toilet working as normal. As usual, Darren was very professional and customer-focused. Highly recommended

Darren replaced a faulty controller panel, having very kindly come out 2 days earlier at very short notice.
As usual, an absolutely first class service. The efficiency in terms of fault diagnosis and then coming back to replace the panel having sourced the part in very quick time was excellent. Thank you.

Prompt and efficient
The booking system is easy and it was good to get a specific time for the call out for a boiler problem. Darren diagnosed the issue quickly and provided a quote for the repair work promptly. He was accommodating in returning quickly, and the problem is sorted. He is personable, and I wouldn’t hesitate to recommend him for boiler issues.

Mixer tap installation covered by 'Heat Club' membership
We pay a monthly 'Heat Club' subscription to Heatco. This covers annual boiler, central heating and gas fire servicing and callout when there's a problem. But it also covers small plumbing jobs – as we were reminded when we needed to replace a leaking mixer tap. We paid for a new tap, but Heatco installed it – quickly and efficiently – without an additional labour charge.

Gas Fire Service Safety Check
Darren arrived on time, is very courteous and a pleasure to deal with. Darren undertook his work diligently, cleaned up any mess and left the area round the fireplace in a clean and tidy condition. I would have no hesitation in recommending Darren's work.

You can trust them
Have been using HeatCo for a few years and found them to be very efficient and extremely trustworthy. Tried other companies (for various things that Heatco doesn't normally do) and have sometimes been quoted several times higher for the same thing or had unnecessary work suggested. Highly recommend!

Darren from HeatCo serviced our boiler again yesterday and as always did a great job. He arrived promptly, with advance warning, and carried out the service with a minimum of disruption. We're very happy to recommend HeatCo to others. The service is great.

Always reliable and efficient
Have used Heatco both for individual jobs such as moving rads and also signed up for the annual maintenance plan. The annual maintenance plan covers the boiler servicing and has taken out any worries and associated costs with unexpected problems that inevitably pop up over time on most systems. Individual jobs have always been done on time and competitively. Highly recommend.

Efficient and good value
I have used HeatCo to service my old boiler and replace it with a new one. They are efficient, courteous and professional. The cost of replacing the boiler was good value. The payment method and invoices were clearly explained and worked well. You also get text messages about their arrival time. Highly recommend.
